Comparative study between different schedules for sclerosing oesophageal varices.

Area of Science:

• Gastroenterology
• Endoscopic procedures
• Vascular interventions

Background:

• Esophageal varices pose a significant bleeding risk in patients with portal hypertension.
• Sclerotherapy is a common endoscopic treatment for esophageal varices.
• Optimizing the interval between sclerotherapy sessions is crucial for effective treatment and patient outcomes.

Purpose of the Study:

• To compare the efficacy and safety of one-week versus two-week intervals for esophageal variceal sclerotherapy.
• To evaluate differences in treatment duration, sclerosant volume, and complication rates between the two interval groups.

Main Methods:

• A comparative study involving two groups of patients undergoing sclerotherapy for esophageal varices.
• One group received sclerotherapy at one-week intervals, while the other received it at two-week intervals.
• Data collected included total sessions, sclerosant volume (5% ethanolamine oleate), complication rates, and time to variceal eradication.

Main Results:

• No significant differences were observed in the total number of sclerotherapy sessions, total sclerosant volume, or complication rates (pyrexia, stricture ulcer, slough formation) between the one-week and two-week interval groups.
• No early or recurrent bleeding events occurred in either group.
• Variceal eradication was achieved significantly earlier in the two-week interval group compared to the one-week interval group (P < 0.05).

Conclusions:

• A two-week interval for sclerotherapy may lead to more rapid eradication of esophageal varices compared to a one-week interval.
• Both one-week and two-week intervals appear to be safe and equally effective in terms of total sessions, sclerosant volume, and complication rates.
